THILL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 458,310, dated August25, 1891. Application iiled January 3, 1891. Serial No. 376,580. (Nomodel.)

To all whmn it nza/y concern,.-

Be it known that I, ELIHU WILDER, of Newton, in the county of Middlesexand State of Massachusetts, have invented certain new and usefulImprovements in Devices for Preventing Rattlingin Thill-Couplings, ofwhich the following is a specification.

This invention is an improvement in devices for preventing rattling inthill-coup lings.

This invention has for its object to provide an adjustable springadapted to be interposed between the thill-iron and the clip of the axleto preventrattling ot the thill-cou plings; and it consists in a springcomposed of two parts, one of which has a bearing on the other, wherebyit may be rocked, the two parts being connected by suitable means whichpermit the adjustment of the parts to the distance between the clip andthe socket of the thill-iron, as I will now proceed to describe.

In the accompanying drawings, forming a part of this specication,Fig-urel represents a transverse section of a carriageaxle, showing one form ofmy improved device. Fig. 2 represents a similar view showing amodification. Fig. 3 represents a top view.

The same let-ters of reference indicate the same parts in all thefigures.

In the drawings ct represents an axle, and b the clip, which is securedin the usual manner to the axle and has theiears b', which receive thebolt c, that connects the socket d of the thill-iron to said ears.

In carrying out my invention I provide an anti-rattling spring composedof two parts or members e e', which are interposed between the clip band the socket d, said members being composed of strips of steel orother suitable metal. The member e bears againstone side of the clip andmay be attached thereto by' screws or not7 as may bev preferred. Theother member e is formed with a concavity, which ts the curvature of theinner side of the socket d, and is adjustable toward or from the membere by an adjusting device supported jointly by the two members e and e.In Figs. l and2 I have shown the said adjusting device as composed of ascrew g,

passing through oritices in the lower ends of the members e e. In Fig.lsaid screw is shown as provided with a nut h and with a head h', saidhead bearing against the member e, while the nut bears against themember e. In Fig. 2 the screw has no uut and works in a threaded oriiicein the member e. The member e is curved inwardly at e to form a fulcrumor rest adapted to bear upon the member e above the screw g. It will beseen that by adjusting the nut 7L or turning the screw g, so as to forcethe lower ends of the members e and e toward each other, the concave endof the member e will be forced outwardly and caused to bear with anincreased pressure on the socket d, vwhile by an opposite adjustmentofthe screw the pressure of the member e upon the socket may bedecreased. It will be seen that by this device I am enabled to adjustthe pressure upon the socket d and accommodate the adjusting device tothe width of the space existing between the clip b and the socket d.

To prevent the accidental rotation of the screw g or the nut h, Iprovide the plate or member e with one or more outwardly-bent ears e3,which bear on the sides of the nut h, as in Fig. l, and against the headof the bolt g, as in Fig. 2. The member e is shown in Figs. l, 2, and etas provided with a horizontal ear e4, bearing on the upper ends of theclip-ears b and constituting a desirable nish. Said ear e4 also supportsthe device and prevents it from dropping through the space between theclip and the socket d.

I claiml. The improved anti-rattling device for thill-couplings,composed of the spring memberse e', formed to be interposed between theclip and the socket of the iron, one of said members having a concaveportion formed to receive the socket of the thill-iron and beingfulcrumed on the other member, the adjusting bolt or screw connectingthe outer ends of said members, and the ear e4, formed on one of themembers and arranged to bear on the ears ot' the clip, as set forth.

2. The improved antirattling device for thill-couplings, composed of thespring inembers e e', formed to be interposed between Ico the clip andthe socket of lLhe iron, the ad j usting bolt or screw connecting theouter ends of said members, and the eau1 or ears e3, formed on one ofsaid members to prevent the loosen- 5 ing of the bolt or screw, as setforth.

In testimony whereof I have signed my name to this speecaton, in thepresence of two subscribing Witnesses, this lst day of January, A. D.1891.
